[0021] The specific technical solutions of this utility model are further described below with reference to the accompanying drawings, so as to enable those skilled in the art to further understand this utility model, without constituting a limitation on its rights.

[0022] Example 1, referring to Figure 1-3 An environmentally friendly inner core component for an oil mist filter, comprising:

[0023] The inner core body 1 is formed into a cylindrical structure. Its size can be customized according to the specific size of the oil mist filter. One of its flat ends is open to facilitate the discharge of purified gas. Several wedge-shaped placement grooves 2 are opened on the outer peripheral surface of the inner core body 1, forming roughly square grooves.

[0024] Several arc-shaped filter frames 3 are formed into a roughly fan-shaped structure. Each arc-shaped filter frame 3 is provided with a connecting mechanism, which includes an inner connecting plate 4 and an outer connecting plate 5. Both the inner connecting plate 4 and the outer connecting plate 5 are formed into roughly square plate structures. The inner connecting plate 4 is fixed to the inner wall of the wedge-shaped placement groove 2, and each wedge-shaped placement groove 2 has four inner connecting plates 4. The outer connecting plates 5 are fixed to the arc-shaped flat end face of the arc-shaped filter frame 3, and each arc-shaped filter frame 3 is equipped with four outer connecting plates 5. The number and size of the inner connecting plates 4 and the outer connecting plates 5 can be adjusted according to the needs of use. The inner connecting plate 4 and the outer connecting plate 5 are provided with a number of threaded holes at intervals at corresponding positions. The inner connecting plate 4 and the outer connecting plate 5 can have three bolt holes, and the number can be selected according to the usage requirements. The arc-shaped filter frame 3 is fixed in the wedge-shaped placement groove 2 by the bolt fasteners placed in the threaded holes. The inner core body 1 is provided with three layers of wedge-shaped placement grooves 2 along its axial direction, namely upper, middle and lower. Each layer of wedge-shaped placement grooves 2 has four wedge-shaped placement grooves 2 arranged at equal intervals. The number of wedge-shaped placement grooves 2 in each layer can be selected according to the usage requirements and is not limited to this.

[0025] Oil mist filter 6 is used to filter oil mist. It has mesh holes, and the mesh size can be selected according to the usage requirements, so the specific value will not be described here. It is embedded in the middle of the arc-shaped filter frame 3 to filter oil.

[0026] In other words, each arc-shaped filter frame 3 with an embedded oil mist filter screen 6 and the inner core body 1 are detachable. Any one or more arc-shaped filter frames 3 can be disassembled for cleaning or repair and replacement. Compared with the previous method of only replacing the inner core of the oil mist filter without maintenance, the detachable structure can greatly reduce the cost of use and achieve cost reduction and efficiency improvement to a certain extent.

[0027] An inner sealing groove 7 is provided in the middle of the wedge-shaped placement groove 2 of the arc-shaped filter frame 3. The inner sealing groove 7 is formed into a roughly trapezoidal groove structure. An outer sealing groove 8 is provided in the middle of the flat end face of the arc-shaped filter frame 3 facing the wedge-shaped placement groove 2. The outer sealing groove 8 is formed into a roughly trapezoidal groove structure. After the arc-shaped filter frame 3 is placed in the wedge-shaped placement groove 2, the inner sealing groove 7 and the outer sealing groove 8 are spliced ​​together to form a square groove. A sealing strip 9 is also provided between the inner sealing groove 7 and the outer sealing groove 8. The sealing strip 9 is formed into a roughly square strip. Its size can be selected according to the usage requirements. The sealing strip 9 is fixed on the bottom of the inner sealing groove 7. The thickness of the sealing strip 9 is half the thickness of the inner core body 1 and the arc-shaped filter frame 3.

[0028] It is important to note that when the arc-shaped filter frame 3 and the inner core body 1 are designed as a detachable assembly structure, it is necessary to improve the sealing performance between the two. A sealing strip 9 is added at the joint between the arc-shaped filter frame 3 and the wedge-shaped placement groove 2. After the arc-shaped filter frame 3 and the wedge-shaped placement groove 2 are connected by threads through the inner connecting plate 4 and the outer connecting plate 5, the mechanical sealing performance between the two is improved by the compression of the sealing strip 9 between the arc-shaped filter frame 3 and the wedge-shaped placement groove 2. This ensures that the oil mist gas can only be discharged to the outside of the oil mist filter through the oil mist filter screen 6, thus guaranteeing its basic filtration capacity.

[0029] When using the environmentally friendly inner core component of the oil mist filter in Example 1, it is only necessary to install the arc-shaped filter frame 3 onto the inner core body 1 with bolt fasteners, and then load the assembled inner core body 1 onto the oil mist filter. The inner core body 1 of the oil mist filter can be cleaned periodically by removing the arc-shaped filter frame 3 from the wedge-shaped placement groove 2. Compared with the previous method of simply replacing the inner core of the oil mist filter without maintenance, the detachable structure can greatly reduce the cost of use.
